Product features

5-chamber system with an installation depth (frame width) of 70 mm providing thermal protection at a very high level.

The thickness of the external walls of the profile ≥ 2.8 mm, that is, parameters that meet the highest RAL standards – “Class A”.

Arrangement of two external seals to ensure very good tightness, sound insulation and thermal insulation.

Smooth, easy-care and maintenance-free profile surfaces made of high-quality PVC.

Where are Perfectline system windows most often installed.

In multi-family buildings on floors above the fourth floor. The technical parameters of the Perfectline system guarantee high resistance to adverse weather conditions including strong wind pressure.

In single-family houses, where the color of the windows creates a coherent whole with the image of the entire house.

In all buildings with high thermal insulation parameters. Windows in the Perfectline system with glazing with a coefficient of Ug = 0.7 guarantee high thermal insulation protection.

Additional equipment that customers decided on when buying windows in the Perfectline system:

The dual-function element is a handle rotation lock with a sash lifter. This mechanism prevents the sash from tilting when the window is open. Thanks to it, there will be no “unhooking” of the sash from the upper hinge. The elevator slightly lifts the sash and ensures its smooth transition from open to closed position. This function is especially recommended for large windows.

The MSL mechanism is responsible for the graduated tilt. Instead of one position, we get 5 positions of the tilted sash by turning the handle to the next “step”. The tilted sash is also secured against slamming. Thanks to MSL we regulate the intensity of ventilation

The multifunctional element combines the function of the handle rotation lock and lift with the balcony latch. When going out to the balcony, you close the door by pulling a special handle. The latch holds the sash in the frame. The door will open again with light pressure from the outside.

VENTAIR pressure ventilators are equipped with a self-acting flow regulator (which reacts to the pressure difference), thanks to which the amount of supplied air is constant, independent of atmospheric conditions (wind, cold). In addition, they allow manual adjustment up to and including closure.
